60℃下,在体积比为1∶1的乙醇水溶液中,采用常规溶液法合成了钐(Sm)-对苯二甲酸(1,4-H2bdc)-1,10-菲咯啉(phen)三元配合物。利用元素分析(EA)、红外光谱(FTIR)、热分析(DSC-TGA)、紫外-可见分光光度计(UV-Vis)和荧光分光光度计(FS)等分析手段对配合物的组成和光学性能进行了分析与表征。结果表明,对苯二甲酸的羧基氧原子和1,10-菲咯啉的氮原子均与Sm3+配位,三元配合物的组成为Sm(1,4-Hbdc)phen.2H2O,并具有荧光性能。
Sm (1,4-H2bdc) -1,10-phenanthroline (tris (triphenyl) tris-p-toluenesulfonate) was synthesized by the conventional solution method at 60 ℃ in ethanol solution with a volume ratio of 1: Yuan complex. The composition and optical properties of the complexes were characterized by elemental analysis (EA), infrared spectroscopy (FTIR), thermal analysis (DSC-TGA), UV-Vis and fluorescence spectroscopy (FS) Performance was analyzed and characterized. The results show that both the carboxyl oxygen atom of terephthalic acid and the nitrogen atom of 1,10-phenanthroline are coordinated with Sm3 +, and the composition of the ternary complex is Sm (1,4-Hbdc) phen.2H2O with fluorescence performance.
